ICE-CREAM FREEZER.

Specification of Lettersl Patent.

Patented Oct. 23, 190B.

Application iiled Julie 25, 1904. Serial No. 214.122.

To a'fZZ whom it may concern:

Be it known that I, THOMAS J. FE'GLEY, a citizen of the United States, residing in Phil'- adelphia, Pennsylvania, have invented cerjtain Improvements in Ice-Cream Freezers, of which the followin is a specification.

The mainobject of my invention is to so construct the operating mechanism of anicecream freezerl that it can be cheaply made, readily assembled or taken apart, and which will require very little fitting, yet when the parts are together it will be substantial and easily operated.

A further object of the invention is to so construct a lreezer of the reciprocating type as to cause the Scrapers of the dasher to au'- tomatically adjust themselves in position to scrape the can.

These objects I attain inthefollowing manner, reference being had to the accompanyin drawings, in whichigure l is a plan view of an ice-cream freezer illustrating my invention. Fig. 2 is a vertical sectional view on the line 2 2, Fig. 1. Fig. l3 is'a sectional plan view of the can on the line 3 3, Fig. 2. Fig. 4 is an venlarged view showing the operating mechanism in detail. Fig. 5 is a section on the line 5' 5, Fig. 4. Fig. 6 is a perspective view showing the details of the operating mechanism detached. Fig. 7 is a perspective view ofthe top of the can. Fig. 8- is a view illustrating my invention in connection with a freezer 1n .which both the dasher and the can rotate,

and Fig. 9 is a view showing another modifi'- cation of the invention.

A is the tub of an ice-cream freezer, in which is mounted the can B.

D is the cross-frame, which is -attached to the tub, as clearly shown in Fig. 1. Projections d d on this cross-frame enter openings in the casting a, secured to one side of the tub, and the opposite end o1 the fr'ame is clamped in the present instance to a casting a by means of a clamping-lever 0.2. This clamping means forms no part of my invention.

The canBhasa central projection b,mount ed on a bearin C, secured to the bottom of the tub. This earing has arms c,which prevent the can tipping to any great extent and allow for the packing of the ice under the can. The can has atop B', which is secured to the can in any suitable manner.

On the frame D is a projecting stud D', which has a portion d extending into a cavity c in the head of the dasher E. The lower end of the dasher fits into a cavity b in the bottom of the can B. Thus the dasher is held centrally, yet the can is free to reciprocate or rotate around it.

1F is a bar mounted in bearings d2 and d4 on the frame D and carrying at its end asupport G, having arms g g, forming a fork-which engages the hub @l of the segmental gear'I. This segmental gear is mounted on a portion d3 of the stud D and hasl a flan et', which rests upon the arm g of the forke support G, so that when the parts arein positionthe support G will hold the segmental gear I inproper position on the stud D', preventing it becoming detached when the cross-framev D is removed from the tub.

J is a toothed structure in the form of a segmental gear having teeth which mesh with the teeth lof the gear I, and this gear is mounted on the bar F between the bearing d2 and the support Gf In the present instance this gear is loose on said bar and has an arm j, which is preferably s uared, so that an operating-lever J can be p aced over the squared portion of the arm for the purpose of reciprocating the gear J, as my invention, as shown in Figs. l to 7 inclusive, is adapted to a reciprocating freezer.

The bar F is held in position by a pin f, which passes through a suitable openin therein directly back of the bearing d2, an as this bar need not necessarily rotate it simply acts as a support for the segmental gear J and the detachable support G.

On theunder'side of the gear I in the present instance are twolugs t2, which enter cavities b2 in the projections b3 ofthe cap B of the can, so that when'the parts are assembled as shown in Fig. 2 and the lever J is reciprocated its motlon will be imparted, through the gears J and I, to the can, which will also be reciprocated.

The can B in the present instance has a partition m, dividing the can into two parte for the purpose of enabling'the user to freeze two kinds of ice-cream kat once, and the dasherEis made in two parts E E2 to straddle the partition, one art being on one side of the partition and t e other on the opposite side. The partition is recessed, as shown lin IOO Fig. 3, to enable the stem e to be in the central position.

On each of the sections are arms e2,in which areopenings for the reception of the pivotpins n n of the scrapersN. Each scraper N is made double, having two blades n n2, one projecting on one side of the center and the other on the opposite side, and these blades preferably rest on the bottom of the can, as shown in Fig. 2. j

When the can is moved in the direction of the arrow, Fig. 3, the friction of the bottom of the can against the end of the blades will cause the blade n to move out in the direction of the arrow on its pivot against the body of the can, scraping it and removing the frozen material from the can, while the other blade n2 is moved away from the body of the can, but causes the material which is not in a frozen state to be forced against the body of the can, thus producing the best action possi- .ble for evenly freezing the material.

.When the can is reversed, the blade n2 is forced against the body of the can and the bladen withdrawn. Thus inreciprocatingthe can by the mechanism above described the blades scrape the surface of the can and rapidly freeze the material in the two sections of the can.

It will be understood that while my invention is particularly adapted for this class of freezers it can be used as well with a freezer in which the can is rotated in one direction,

' or in which thel can is rotated in one direction and the dasher in the opposite direction, or in a freezer where the dasher only is rotated.

Itwillbe seen in referring to Figs. 2, 4, and 5 that the parts canL be readily assembled without requiring to be finished to any great extent, and when 'assembled the parts will be held in proper alinement, so as to make the working 'of the mechanism easy, and when it is wished to .detach the elements all that is necessary is to withdraw the pin f from the bar F, yremove thel bar, when the two segmental gea'rs'J and I and the support G will j immediately become detached.

It will be understood that in designing the operating mechanism of an ice-cream freezer the parts must be so formed that the working of the same will not be affected by dampvness or neglect, and they must be made to withstand the rough usage to which devices of this kind are subjected.

' In'Fig. 9 I have shown my invention applied to a machine in which the shaft F is a driven shaft and being turned either by a hand-crank or by power and having secured to it a toothed structure in the form of a beveled gear-wheel J2, which meshes with a gearwheel I on a stud D2, projecting from the frame. The stud has an extension which enters a cavity in the end of the dasher E3,

and the cap of the can is notched to receive the projection on the gear-Wheel. The support G is the same as shown in Fig. 4, and its arms extend on each side of the hub of the wheel I.

In Fig. 8 I have shown a construction in which both the dasher and the can rotate. The shaft F2 has a toothed structure in the form of a gear J 3, which meshes with a bevel gear-Wheel I2, attached to the cap B2, and the wheel J3 also meshes with a bevel-wheel K, mounted on a stud D3, projecting from the cross-frame. The hub of this gear-wheel K, is extended and forms a bearing 7c for the gear-wheel I2 and has an extension k, which enters a cavity in a dasher E4. The support G is mounted on the end of the shaft F2 and is forked to receive the flanged hub of the gearwheel I2. By this arrangement the dasher is turned through the medium of the gears J and K, while the can is turned through the medium of the gears J3 and I2.

I claim- 1. rIhe combination in an ice-cream freezer, of a cross-frame, a bar mounted on the crossframe, a gear-wheel mounted on the crossframe, means engaging the gear-wheel for operating the same, and a support carried by the bar and engaging the gear-wheel so as to retain the gear-wheel in position on the frame, substantially as described.
